“Katy’s friends and family haven’t taken to John at all, in fact they are worried that she is headed for heartbreak,” a source told the site. “She’s been telling everybody who cares to listen how great John is and it’s clear that she is totally in love with him.”

Katy might be wise to listen up as her relationship with John hasn’t exactly been smooth-sailing so far. The couple has already broken up once and reportedly only got back together after John apologized for his womanizing ways.

“Now she appears to have fallen dangerously in love with him and her friends are concerned,” the insider went on. “Now that she has invested more feelings in John and has let her guard down, there’s only one way this can end... in disaster!”
